Part B - The Maintenance Review Board (MRB) Process

Chapter 7. Responsibilities - Industry
a) Type Certificate Applicant

The type certificate applicant is required to:

Present a proposed Policy and Procedures Handbook (PPH) to the ISC, which follows the general guidelines of this Transport Publication.

If an accepted version of MSG-3 is not being used as the analytical logic, perform an assessment of the selected analytical logic using the SAE JA1011 Standard and submit a report of that assessment to the MRB Chairman.

Ensure that the individual ISC and WG members, and each representative of the applicant involved in preparing the analytical analysis for review by the working groups, meet the experience and training requisites of this document or show equivalency, and provide this information upon request to the MRB Chairperson.

Provide aircraft familiarisation training for all members of the MRB, ISC, and WGs.

Provide the ISC with an initial list of Maintenance Significant Items (MSIs) and Structural Significant Items (SSIs), with sufficient data to support the selection criteria for each item.

Provide industry WGs with sufficient technical data to support the analysis of MSIs and SSIs in a timely and adequate fashion.

Provide the ISC and appropriate WGs in a timely manner (90 days) with information concerning certification issues and resolutions regarding proposed tasks originating from the certification process, such as Airworthiness Limitation Items (ALIs) or Certification Maintenance Requirements (CMRs).

Ensure that the manufacturer's ICAs contain information including the procedures necessary to perform all tasks listed in the MRBR.

Participate in ISC and WG activities.

Submit the MRBR proposal to the MRB Chairperson at least ninety days prior to scheduled TCCA approval.
b) Industry Steering Committee (ISC)

The Type Certificate applicant is responsible for the setting up of an ISC. The ISC membership should be comprised of representatives from airframe, engine, propeller, and appliance manufacturers as well as the intended air operators/purchasers and Approved Maintenance Organizations (AMOs). The ISC is to develop and establish policy with regard to procedural matters for the development of the proposed MRBR, direct the activities of the working groups (WGs) and prepare the MRBR proposal.

It is also the function and responsibility of the ISC, under the direction of the ISC Chairperson, to perform the following:

Develop and approve the Policy and Procedures Handbook (PPH) and forward it to the MRB Chairperson for review and acceptance. The MRB Chairperson will direct any resultant comments to the type certificate applicant. (Guidance to be used during development can be found in Appendix 2). The PPH must be approved by the ISC and formally accepted by the MRB Chairperson before WG meetings begin.

Determine the number and type of WGs that will be necessary organise them and appoint an industry representative as chairperson for each WG.

Provide the MRB Chairperson, with a list of the WGs, and the names of ISC and WG members, their affiliation, and any changes as they occur.

Arrange for necessary technical and analytical logic training (at the revision standard being used) for all ISC and WG Members and Regulatory Authority Advisors.

Invite the MRB Chairperson and selected MRB Members to ISC meetings.

Invite other regulatory authorities to ISC meetings, with co-ordination of the MRB Chairperson.

Attend MRB meetings when requested by the MRB Chairperson.

Review all working group analyses and presentations.

Identify analysis to be re-visited by WGs and add justification to ISC minutes.

Provide supporting technical data/analysis for the proposed MRBR.

Document and present the proposed MRBR to the type certificate applicant.

Review and provide comments on proposed revisions to the MRBR.
c) Working Groups (WGs)

WGs should be composed of representatives of the manufacturers, the air operators, and maintenance organisations. A Working Group's responsibilities include the following functions:

Develop initial minimum scheduled maintenance / inspection requirements for new or derivative aircraft, using the latest acceptable revision of the analytical process.

Establish sampling requirements as part of an age-exploration system 11 when the analysis determines that such sampling is applicable and effective to substantiate, the adjustment of task intervals and the identification of new tasks.
d) Sampling Inspections (In support of Age Exploration and MRBR Evolution)

For aircraft and engines where a manufacturer/air operator conducts discretionary or required sampling/analytical inspections in support of age exploration and MRBR evolution, the following procedures apply:

The manufacturer/air operator shall notify TCCA in a timely manner, of the time and place of the inspection, in order to permit regulatory authority participation. Where regulatory authority attendance is not possible, the manufacturer/air operator must provide to the regulatory authority a copy of the inspection report including supporting documentation and any associated analysis, which was conducted to justify the conclusions of the report.

Subsequent to completion of any requisite sampling inspections of a complete product or module, further regulatory authority participation will be determined on a case-by-case basis.
NOTE: The TCCA office responsible for co-ordinating regulatory authority attendance at opportunity and required inspections will be the Superintendent, Aircraft Evaluation Group, Aircraft Maintenance and Manufacturing Branch, Ottawa.

e) Experience and Training Requisites

ISC / WG Air Operator / Purchaser / AMO Representatives must meet the following levels of:


Valid aircraft maintenance engineer (technician) license which meets ICAO Annex 1 criteria or equivalent, practical experience and theoretical training in the disciplines associated with maintenance programmes and their development, or
Practical maintenance experience on an equivalent aircraft type or on systems to that being analysed, or
Practical experience as an Aircraft Maintenance Inspector or Quality Assurance experience.


Training in the analytical logic process that is to be utilised.

ISC / WG Manufacturer Representatives must meet the following levels of:

Have relevant maintenance engineering experience on an equivalent aircraft type, system or component

Training in the analytical logic process that is to be utilised.
